CAM Specs Help

[1979Calais]

The only thing odd I see is that you have the same lift on the int. and ex with it being a split duration cam. It could have been ground that way though, so you could run the same ratio rocker on each valve.

My cam is 212/226 @ .050 with .483/520 lift with a 1.5 rocker. If I ran a 1.6 on the int. it would have .515 lift which is pretty much the same as the ex.

I believe they installed 1.6 rockers.

Yup, high lift and shorter duration is an aspect of roller cams. The specs of the Lunati cam are similar to my Erson hydraulic roller cam. My cam is for fuel injection applications and so is yours. You can't go too radical when choosing a cam and have fi. FI runs off sensors and some necessary sensors rely on vacuum and too much of a cam would kill the much needed vacuum and throw fi parameters off.
